Piezoelectric Haptic Feedback

High-Performance Piezoelectric Haptic Actuators for Touch Communication

Midé’s SHIVR™ high performance, low-profile piezoelectric haptic actuators enable low power, thin, lightweight, and non-magnetic touch communication making them ideal for specialized bio-medical, military and industrial communication applications. SHIVR actuators are able to create a richer haptic experience, as they allow single cycles, fast start-up, static deflection, and independent frequency, amplitude, and phase control capabilities – allowing the user to control the feel and intensity of the sensation.  The high performance and broad array of haptic feedback of the SHIVR actuators are made robust and reliable by utilizing Midé’s patented Piezo Protection Advantage.
